Definitions

  • the invention relates to a ski intended for skiing alpine.
  • a ski is presented like a beam elongated with a gliding sole on its underside, and receiving on its upper face provided retaining elements to hold the skier's shoe.
  • the pressure distribution of the ski on its sliding surface is an important parameter that determines the qualities of skiing and cornering.
  • An object of the invention is to propose a construction of same type which is better suited for wide skis.
  • the ski according to the invention comprises an elongated body, front and rear ends, a gliding sole topped at least one lower reinforcing layer, a core and at least one upper reinforcing layer. It is characterized in that the core has a central core in hard material that spans part of the length and the width of the ski, and a border of softer material which borders the soul on the sides, front and back.
  • the central core is projecting vertically from the rest of the core.
  • skiing is surmounted by two oscillating plates having a surface mounting upper intended to receive elements of retained, the plates being assembled to the ski around an axis transverse carried by the core core.
  • Figure 1 shows in perspective a bare ski according to the present invention.
  • Figure 2 is a sectional view of the ski of Figure 1 to level of its central area.
  • Figure 3 is a sectional view of the ski of Figure 1 towards one of its ends.
  • Figure 4 shows the core core
  • Figure 5 shows the central area of the ski in Figure 1 fitted with plates.
  • Figure 6 is a cross-sectional view of the ski at level of one of the plates.
  • the ski 1 which is represented in FIG. 1 comprises a body elongated 2, with two front and rear ends 3 and 4.
  • the front end 3 is raised and rounded to form a spatula.
  • the end rear 4 is also raised and rounded. This however is not limiting, and we could have one end cut straight as for a traditional ski.
  • the ski 1 has in its lower part a gliding sole 6.
  • the sole is bordered laterally by two side edges 7 and 8.
  • the sliding sole 6 is topped with a layer of reinforcement 9 in resin reinforced with fibers, itself topped with preferably by a metallic reinforcing layer 10, produced especially aluminum. These different layers are housed between edges 7 and 8.
  • nucleus 12 which will be described in detail later.
  • nucleus there is preferably a layer 14 of metal reinforcement which is of the same nature as layer 10. If layer 10 is present, in principle the layer 14 is also present.
  • a upper reinforcement layer 16 made of resin reinforced with a layer of fibers covers the whole in the manner of a shell, that is to say as this layer descends along the lateral flanks up to the side edges.
  • the edges overflow each side over a small width, and the reinforcing layer upper 16 descends until contact with these parts overflowing that it covers.
  • a bonding film is interposed between the metallic reinforcing layers if they are present and the core. These layers were not represented in the figures.
  • the top reinforcement layer is covered with a decorative layer which is also not shown in the figures. This decorative layer is of any suitable and known type.
  • the core 12 comprises two parts main ones of a different nature.
  • the nucleus 12 has a central core 18 made of a relatively hard material, such as wood.
  • the central core extends over a portion only the length and width of the ski.
  • the central core rests vertically on the subassembly lower, i.e. on the reinforcement layer 10 metallic. And it protrudes upward from the rest of the nucleus.
  • the projecting edge 19 is formed by the central core of the core covered with layers upper reinforcement. In the central part of the ski, the projecting edge is relatively wide. Its width is close to that of a traditional ski, around 60 millimeters. This value is not limitative.
  • Figure 4 shows in perspective the core 18 of the core. It is formed for example by an elongated block of wood. The block is narrowed in width towards each of its ends 18a and 18b. In these areas, its thickness is also reduced by machining its upper part. In his middle part 21, the core 18 has lateral edges and faces upper and lower substantially parallel.
  • the soul is made of preferably in wood, for example in beech and poplar glued and it is shaped by machining.
  • the rest of the core which forms the border 22 of the core 18 laterally, on the front and rear is made in one softer and lighter material than the core.
  • the border is in polyurethane foam possibly reinforced with glass fibers.
  • This border is for example made at from a foam bar cut or machined to shape desired, with a central cut in which is housed blade.
  • the central core and the border define two areas of the ski of very distinct altitude.
  • the metallic reinforcing layer 14 if it is present is formed by two parts, a border part 14a which covers the edge of the core and which has a central cutout crossed by the core 18, and a central part 14b which covers the upper face of the central core 18 of the core in marrying its shape.
  • the section of the ski shown in Figure 2 is made in the central area, where we have the core 18 and the border 22 of the core side by side.
  • the section of Figure 3 is made towards either end where the nucleus is formed only by border 22.
  • ski according to this construction method having the following dimensions, length 1950 millimeters, width maximum in spatula 120 millimeters, minimum width in the central zone 86 millimeters, maximum width in heel 115 millimeters, with a core having a core of 1200 millimeters long, 60 millimeters wide, projecting 8 millimeters towards the middle and 1.5 millimeters towards the ends by compared to the rest of the core, the thickness of the ski being 12 millimeters in these border areas.
  • these figures are given as an example only and have no limiting value.
  • the ski of the invention is preferably equipped with two plates 23 and 24.
  • the plates have the same construction, with one side mounting upper 23a, 24a which is intended to be drilled and receive front and rear retainers of a type known.
  • the mounting faces 23a and 24a are maintained slightly raised from the upper surface of the ski.
  • the plates overlap the edge 19 of the ski. They are each formed for example by an aluminum plate or other which is folded to the width of the edge 19 so as to form two lateral wings which descend along the sides of the ridge 19.
  • the plate 23 which is represented in section in the Figure 6 has two side wings 23b, 23c which run along the edge 19.
  • Each of the wings is pierced with an orifice crossed by a screw which is screwed into the core.
  • the assembly screws of a plate are screwed in alignment with each other, so as to define for the plate a transverse axis of oscillation which crosses the core of the nucleus.
  • the ski present in the area of edge of the ridge four low transverse grooves depth 26, 27, 28, 29 in alignment with the housing of the screw.
  • the depth of the grooves is determined to allow the passage of the screw heads.
  • the ski has a small recess in each of the screw housings, to allow the housing of the plate wing.
  • the recesses 34 and 35 for the wings 23b and 23c are visible in figure 6. These different reliefs of the ski are set shape by cutting or machining the core, or other means appropriate.
  • the metal reinforcing layer 14 is shaped to match these reliefs.
  • thin plates 30, 31, 32, 33 of a deformable material for example an elastomer, are inserted between the mounting faces of the plates and the upper surface of the ridge.
  • a deformable material for example an elastomer
  • the two-part core allows a better pressure spreading.
  • the wooden soul stiffens the central part of the ski where most is concentrated large part of the pressure forces. She acts like a beam which spreads over its entire support forces the shoe which are concentrated at the level of the connections between turntables and skiing. As a result, the pressure peaks that one usually meets towards each connection or each retainer are mitigated.
  • the plates oscillating which carry the retainers of the boots release the ski in flexion and ensure better winding of the ski in the curves, hence better driving the ski.
  • the foam part of the core gives to ski lightness, and also a certain flexibility. he is possible this way to build very skis wide, especially in the central area. These skis have a great lift, given their sliding surface. They nevertheless have great maneuverability thanks to the construction particular to the core and to the articulated plates.
  • the core of the hard material core could occupy only part of the thickness of the core.
  • the core would be formed by the same material as the border, in particular foam polyurethane.
  • the core soul would not be in contact direct with the lower sub-assembly of the ski, but would keep nevertheless its function of spreading the pressure on the sliding surface.
  • the elements could be assembled directly on top of the ridge 19 taking advantage of its great width. Under these conditions, we could reduce the altitude difference between the top of the ridge and the rest of the ski. Ultimately, the soul and the border could have substantially the same thickness.
